5005 H34 Aluminium Sheet

Aluminium alloy 5005 is a medium-strength aluminium–magnesium alloy offering excellent resistance to atmospheric corrosion and very good weldability. It is highly suitable for decorative anodising, making it a preferred choice for architectural and aesthetic applications.

Important Note on Anodising:

While alloy 5005 is suitable for anodising, streaking may occur. If a critical or uniform anodised finish is required, “Special Anodising Quality” must be specified at the time of order.

APPLICATIONS

Alloy 5005 is commonly used in:

• Building applications – roofing, cladding, corrugated sheets
• Signage – road signs, nameplates
• Food and chemical processing equipment
• Furniture and interior fittings
• Anodised components
• HVAC equipment
• Packaging applications
• Pipe and tube
• Can bodies

Temper Types

The most common temper for aluminium alloy 5005 is:

H34 – Stabilised temper achieved through low-temperature thermal treatment or heat introduced during manufacture. This process stabilises mechanical properties, relieves residual internal stresses, and generally improves ductility.
